In CS20, the stratified wake of a disk at \(=5 \times 10^4\)  is studied at \(\mbox{\textit {Fr}}={2,10,50,\infty }\) . Apart from a detailed analysis of the decay rates of the mean and turbulent quantities, CS20 links the general evolution of stratified homogeneous turbulence [1]}, [2]} with the evolution of the wake turbulence. As the disk wake evolves, the influence of buoyancy is `felt' by the turbulent motions at progressively smaller scales. First the mean flow and the large scales and later the r.m.s. velocities are affected by stratification. Simultaneously, the horizontal eddies start gaining energy. Based on the strength of these effects, three distinct stages can be identified: weakly, intermediate and strongly stratified turbulence. In CS20, the transition between these regimes is examined and parameterized using local Froude and Reynolds numbers. [3]} also examined these transitions and their link with the evolution of stratified homogeneous turbulence using temporal simulations.
